Polyester spiral mesh belts are the industry standard for this application. They not only transport the rubber threads through the ovens, they also ensure uniform heat and air exposure around every thread — making the belt a direct factor in drying efficiency, curing consistency and thread quality.
The belt runs continuously through the tunnel oven, carrying the threads through two thermal zones. Hot air passes freely through the open spiral structure, drying the threads evenly and then curing them into stable, elastic rubber threads.
Step 1 Thread Feed Fresh latex threads enter the tunnel oven on the moving spiral belt. | Step 2 Drying At 50°C – 130°C, hot air flows through the mesh, evaporating moisture. | Step 3 Curing At 100°C – 170°C the threads cure, stabilizing elasticity and durability. | Step 4 Cooling & Output Finished threads cool and travel safely to packaging stations. |
01 Big Loop Airflow Large loops maximize open area for uniform hot-air exchange | 02 Hydrolysis Resistant Special polyester yarn lasts far longer in hot, humid ovens | 03 High-Temp Stability Heat-set structure holds dimensions up to 170°C peak | 04 Antistatic Protection Conductive wires every 10 cm dissipate static charges safely |

Q1: Why use polyester spiral mesh belts for latex thread drying and curing? They combine heat resistance, air permeability and mechanical strength — transporting the threads while ensuring uniform heat and air exposure for consistent drying and curing. |
Q2: What temperature can the belt handle? Up to 170°C short-term peak and continuous operation up to 150°C — covering drying (50–130°C) and curing (100–170°C) zones. |
Q3: What is the big loop design and why is it recommended? Large spiral loops give higher open area and better airflow, letting hot air reach all sides of the thread uniformly — the most commonly used structure in rubber thread lines worldwide. |
Q4: Why is hydrolysis-resistant polyester used? Normal polyester degrades under high humidity and heat. Hydrolysis-resistant yarn significantly improves belt life in hot, moist ovens and reduces replacement frequency. |
Q5: How does the belt prevent static build-up? Antistatic conductive wires are inserted every 10 cm across the belt width, safely dissipating static charges that could affect quality or pose a fire risk. |
Q6: What loop sizes are available? Spiral loop sizes of 5 mm, 7 mm, 10 mm and 12 mm, with big loop designs preferred for maximum airflow. |
Q7: Can the belt be customized for my oven? Yes. Belts are made to your oven width and thread type, with optional filler yarns, heat-sealed or stitched edges, and endless or pin-joined designs. |
